CVE-2020-1597 – ASP.NET Core Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-1597
A denial of service vulnerability exists when ASP.NET Core improperly handles web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against an ASP.NET Core web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the ASP.NET Core application. The update addresses the vulnerability by correcting how the ASP.NET Core web application handles web requests. Se presenta una vulnerabilidad de denegación de servicio cuando ASP.NET Core maneja inapropiadamente las peticiones web, también se conoce como "ASP.NET Core Denial of Service Vulnerability". A flaw was found in ASP.NET Core. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WH5FQ5VT3JGHXFXOETHCTBWJUIAPGHHT https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZW4CBI26KSO3PRL3HLVVISXPPOYUHSXO https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1597 https://access.redhat.com/security/cve/CVE-2020-1597 https://bugzilla.redhat.com/show_bug.cgi?id=1861110 • CWE-400: Uncontrolled Resource Consumption •
CVE-2020-1161 – dotnet: Denial of service due to infinite loop
https://notcve.org/view.php?id=CVE-2020-1161
A denial of service vulnerability exists when ASP.NET Core improperly handles web requests, aka 'ASP.NET Core Denial of Service Vulnerability'.
